Granulomatous rosacea

Granulomatous rosacea is a subtype of rosacea, a skin condition characterized by redness, flushing, and pimple-like bumps on the face. It is characterized by the presence of firm, raised, yellowish-red papules or nodules that are surrounded by an area of redness. These papules can be painful and can last for months or even years. Granulomatous rosacea is considered a severe form of rosacea and can cause significant discomfort and disfigurement. It is typically treated with a combination of topical and oral medications, including antibiotics and steroids.

Granulomatous rosacea is a subtype of rosacea, a chronic skin condition characterized by redness, pimple-like bumps, and thickening of the skin on the face. The term “granulomatous” refers to the formation of granulomas, which are clusters of immune cells that form in response to foreign or irritating substances in the skin. In granulomatous rosacea, these granulomas occur in the affected skin and contribute to the formation of papules and pustules, which are raised, inflamed bumps. This subtype of rosacea is relatively rare and is typically seen in middle-aged or older individuals with fair skin. It is important to seek treatment from a dermatologist for granulomatous rosacea as the symptoms can be persistent and difficult to manage without medical intervention.


The exact cause of granulomatous rosacea is unknown, but there are several theories about its development.

  1. Immune System Response: It is believed that granulomatous rosacea may be caused by an abnormal immune system response, where the body’s immune cells attack the skin, leading to inflammation and the formation of granulomas.
  2. Bacterial Infection: Some studies suggest that a bacterial infection may play a role in the development of granulomatous rosacea. This theory suggests that a bacterial infection triggers an immune system response, leading to granuloma formation.
  3. Genetic Factors: It is also believed that genetic factors may contribute to the development of granulomatous rosacea. This means that a person may have a genetic predisposition to the condition, making them more likely to develop it.
  4. Environmental Factors: Exposure to environmental irritants, such as wind, cold, sun, and heat, can also trigger granulomatous rosacea in some people.

Regardless of the cause, granulomatous rosacea can lead to significant discomfort and cosmetic concerns, and requires prompt treatment. A dermatologist can diagnose granulomatous rosacea and recommend appropriate treatment options.


Some common symptoms of granulomatous rosacea include:

  1. Bumps: These raised, yellowish bumps are often found on the cheeks, nose, and forehead. They can be itchy, painful, or even discharge fluid.
  2. Skin thickening: The skin on the affected area may become thick and leathery, especially on the nose.
  3. Redness: Granulomatous rosacea may cause redness and flushing, especially after exposure to heat, alcohol, or spicy foods.
  4. Burning and stinging: People with granulomatous rosacea may experience a burning or stinging sensation on their skin.
  5. Eye symptoms: Some people with granulomatous rosacea may experience eye symptoms, such as redness, itching, and tearing.
  6. Systemic symptoms: In rare cases, granulomatous rosacea may cause symptoms such as fatigue, weight loss, and joint pain.

It is important to seek medical attention if you have any of these symptoms. Granulomatous rosacea can be treated with medications and lifestyle changes, but early diagnosis and treatment can help prevent complications.


It is diagnosed based on a combination of clinical symptoms and examination findings.

The following tests may be performed to confirm the diagnosis:

  1. Physical examination: A dermatologist will examine the skin and look for the characteristic signs of granulomatous rosacea, such as red, raised bumps with a yellow center.
  2. Skin biopsy: A small sample of skin may be taken and examined under a microscope to confirm the presence of granulomas, which are clusters of immune cells that form in response to an infection or inflammation.
  3. Blood tests: Blood tests may be done to check for underlying health conditions that could be contributing to the skin symptoms, such as an autoimmune disorder.
  4. Microscopic evaluation: A dermatologist may use a special instrument, such as a dermatoscopy, to examine the skin and identify specific features that are indicative of granulomatous rosacea.
  5. Microscopic examination of scrapings: The dermatologist may scrape off some of the raised skin and examine it under a microscope to check for bacteria or other signs of infection.
  6. Skin culture: A sample of the affected skin may be taken and cultured to identify any underlying infections.
  7. Imaging tests: Imaging tests, such as X-rays, CT scans, or MRI, may be performed to rule out any underlying medical conditions that could be contributing to the symptoms.

It is important to note that the diagnosis of granulomatous rosacea is based on the presence of specific symptoms and signs, and there is no one specific test that can definitively diagnose the condition. A dermatologist will typically consider the results of multiple tests, along with a patient’s medical history, to make a diagnosis.


Treatment options for granulomatous rosacea include:

  1. Antibiotics: Tetracycline, doxycycline, minocycline and metronidazole are commonly used antibiotics to treat granulomatous rosacea. These antibiotics help to reduce inflammation and improve the appearance of skin.
  2. Topical medications: Topical metronidazole, azelaic acid, and ivermectin can also be used to reduce inflammation and improve skin appearance.
  3. Isotretinoin: This oral medication is used to treat severe forms of acne, including granulomatous rosacea. It helps to reduce inflammation, unclog pores, and improve skin appearance.
  4. Surgical treatments: In some cases, surgical treatments such as laser therapy or surgical excision may be recommended to remove the affected skin.
  5. Lifestyle changes: Simple lifestyle changes such as avoiding triggers, protecting skin from the sun, and using gentle skin care products can also help manage granulomatous rosacea.

It is important to note that treatment for granulomatous rosacea may need to be adjusted or changed over time to best manage symptoms. Consult a dermatologist for the best treatment plan for you.
